wiring diagram for dune buggy

[BL3Manx]

Well, it sounds to me like its still wired wrong but if it starts and runs OK, then leave it alone.

Like Dale has said before, when working on wiring, your best friend is a test light.

If you decide you want to get it straight, the way to do it is

First disconnect everything from the switch

Next connect the heavy gauge wire from the stud on the solenoid to the terminal marked battery.

Next use a test light to determine which terminals are hot when the key is in the different positions.

The accessory terminal should be the only one hot (besides the battery terminal which is always hot) when the key is turned left.

None should be hot when the key is turned one position right

Ignition and Accessory should both be hot when the key is in the second postion right.

Start, and Ignition should both be hot in the final position right (with spring return).


After you confirm that the appropriate terminals are hot at each switch position,

Connect the Ign terminal to the positive side of the coil

Connect the Start terminal to the spade connector on the starter solenoid

Connect any other wires to the Accessory terminal

i just did the dimmer relay but I used a 67 turn signal switch. It is not a typical relay but is momentary contact switched. It then stays in that position until a momentary contact makes it move back.

The relays are available used on theSamba and also I think www.CIP1.com carries them new.

It works well.

I wired my buggy based on the 1967 wiring diagram and then modified a few things to use relays.

The 67 is the first year of 12 volt therefore it is quite a simple system. If you use taillights from a bug You can pretty well follow it all and change a few things to your taste.

Dale, You have the fuse block unswitched. I run my power to the fuse block from the accessory terminal. That way nobody(kids) can turn on the lights, etc. w/o the key. Its no fun leaving a buggy parked and coming back to a dead battery.

on the diagram you posted im having trouble with alternator, starter and ignition switch. Do i need a 6v voltage regulator

12v with alternator and ignition switch, having trouble looking at the diagram as far as what wires go to the alternator, starter and ignition switch to the fuses

Spike, Dales drawing he posted above is a very basic, no frills wiring diagram. In this thread, on pages 1 and 2 Dale addresses the different starter switches and the wiring for them.

You need to determine what kind of switch you have (not brand name, but how many terminals on the back and what they do. A ohm meter can be used to track down which terminals are momentarly switched to go to the starter and which are switched to run power to a coil), then look at this thread to see which wires go where.

For the alternator, you need to determine if it has an internal regulator or needs an external regulator. This can be determined by what terminals are on the outside of the alternator.

DO NOT use a 6V regulator on that alternator.

Where are you located? VW's were every where, around every corner at one time in the past and the people that still have them are plentyful, and like to help others. You may need to find some other VW airheads in your area to help get you started in the direction you need to go. Not wire your project for you, because you will never learn that way, but identify what parts are what and let you know where the wires need to be run.
